Spartan Advanced Protection System® (APS)
▪ Spartan Safe Haul™ The industry’s only factory-chassis integrated air supply for tow vehicle brake systems.
▪ Collision Mitigation with Adaptive Cruise Control alerts the driver of potentially dangerous driving scenarios and adjusts speed to maintain a safe following distance.
▪ Electronic Stability Control (ESC) helps the driver maintain control of the coach in extreme steering manuevers by automatically controlling individual brakes to help keep the coach moving in intended direction.
▪ Automatic Traction Control (ATC) helps the driver maintain traction under the drive axle tires in slippery conditions by automatically applying brakes on the wheel end that is slipping. This helps transfer power to the wheel end with more traction.
▪ Tire Pressure Monitoring System (TPMS) displays tire pressure and temperature for individual tires. The system will alert the driver if any tire pressure or temperature exceeds set thresholds. The system is expandable to monitor towed vehicles as well.
